DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN DISPENSING APPARATUS Application filed March 8, 1930, Serial No. 434,249. Renewed June 9, 1932. I

My invention relates to dispensing apparatus, and particularly to a dispensing device rendered operative by the insertion of .a proper coin to dispense a gas-charged beverage, such as ginger ale.

The general object of the invention is to produce a simple, inexpensivelvmanufac- I tured, reliable and efficient device which, after insertion of a proper coin and turning of a lever by the purchaser, operates to dispense a drinking cup and deliver a charge of beverage thereto, with the pressure of the beverage assisting in automatically controlling the various steps of the measuring and dispens ng operation and restoration of the operat ng parts to normal position after a dlspenslng operation.

The various features of construction, arrangement and operation of my invention are incorporated in the structure on the draw in s, in which drawings:

*igure 1 is a front elevation of the devlce with the cover .removed to show the dispensa tion controlling apparatus;

Figure 2 i" a rear elevation of the dispensing apparatus supporting panel, showing particularly the measuring element and the valve mechanism for controlling the flow;

Figure 3 is a front elevation of the'cover ofthe device, showing the'arrangement of the coin insertion and coin return openings and the lever by means of which the dispensing device is set in operation;

Figure 4 is a rear elevation of the cover, showing the coin-controlled elements for cooperating with the dispensing mechanism shown in Figure 1, and

Figure 5 is a side elevation of the cover and parts supported thereon.

Describing first the coin-receiving and controlled mechanism shown in Figures 3, 4 and 5, the cover panel 1 has the coin inlet 2, which, in'this case, is intendedv for the reception of nickels. Below this coin inlet the panel journals a shaft 3 having at its outer end the main operating lever or handle 4 which is turned in clockwise direction b the )ury chaser after he has inserted a nickel in the coin inlet. Secured on the inner side of the panel is the coin chute 5 which extends between the inner end of the coin inlet and the coin-receiving disc 6 secured to the inner end outlet end of the coin chute, so that, if a' proper coin C is inserted, it will pass down the chute and be deposited in the pocket. The disc 6 has a stop notch 8 in which the end of a pawl 9, pivoted at 10, is normally held by means of a spring 11, this pawl serving to prevent turning of the shaft 3 in counterclockwise direction by thepurchaser.

A spring 12 is anchored at one end to a post 13 and at its other end is secured to thedisc 6 by means of the post 14, the spring, intermediate'its ends, having convolutions 15 which surround the hub 16 extending from the panel 1 and journalling to shaft 3. The spring tends to hold the disc 6 in normal 0'- sition' with its notch 8 receiving the paw 9 and with its coin pocket 7 below the coin chute, as shown in Figura A cylindrical post or roller 17 on the disc 6 is adapted, when the disc is turned in clock- Wise direction by the turning of the handle 4 by the purchaser, to engage with thedispensing controlling mechanism in a manner to'be hereinafter more fully described.

A detent pawl 18 is pivoted at its outer end on a post 19 extending from the panel 1 and has its inner end shaped to fit in the coin pocket 7 when the disc 6 is turned in clockwise direction and when there is no coin in the pocket. A spring 20 holds the pawl to the disc and normally with its end against the cylindrical surface of the disc just in ad- Vance of the coin pocket. If a proper coin has been inserted, it will pass through the chute and drop into the coin pocket 7 and then, upon rotation of the disc by the purchaser, the coin will engage with the pawl 18 and prevent the pawl from dropping into the pocket, and the disc can then be rotated a sufficient distance to carry the pocket around so that the coin may drop therefrom by gravity, and also a sufficient distance to cause eflective operation of the dispensing mechanism by the engagement therewith of the post or roller 17. However, if a coin has not been received by the coin pocket and attempt is made to turn the disc by means of thehandle 4, the disc will rotate only a short distance until the pawl 18 is received in the empty coin pocket, as the abutting engagement of the disc with the pawl will then prevent further rotation and, consequently, the machine dispensing mechanism will not be operated.

After an operation of the lever 4 in clockwise direction and then release thereof, the spring 12 will restore the disc 6 to normal position with its notch 8 receiving the stop pawl 9. Thus, the lever 4 cannot be turned in counterclockwise direction, and can be turned only a short, ineffective distance in clockwise direction if a proper coin has not been inserted into the machine.

A magnet 21 is provided to deflect magnetic-coins or tokens from the main chute into a return chute 22 which discharges the false coin or token into the cup 23 on the ma-' chine cover. The'chute 5 also has an outlet 24 for coins smaller than nickels, which coins, upon reaching this opening, willbe deflected by a spring 25 and will drop to the bottom of the machine housing.

Referring now to Figure 1, the dispensing controlling apparatus is mounted behind the cover panel 1 on a panel 26 supported on a plate or frame 27. Mounted on the panel 26 is a base plate 28 from which rises a stop post 29 from whose upper end extends the arm 30 terminating in a hub 31. Between the base and the arm is an actuating disc 32 which is rigidly secured on a shaft 33, which shaft is in axial alinement with the shaft 3 and is journalled in the hub-31 and the base plate carries at its outer end a lever 34 which is in the path of the post or roller 17 on the'disc 6 which is turned by the prospective purchaser when he turns the shaft 3 by means of the lever.4. The disc 32 has spaced apart stop arms 35 and 36 for abutting against the post 29 in different positions of thedisc. A spring 37 is anchored at oneend on the stop post 29 andits other end is secured to the lever 34, the spring, intermediate its ends, having convolutions 39 surrounding the shaft 33, the spring tending to hold the disc 32 with its stop 35 against the post. 29 and to resist rotation of the disc in clockwise direction when Q the lever 4 is turned by the purchaser.

Fulcruined on the shaft 33 to swing thereon and extending upwardly therefrom is the actuating lever 40which is held in normal position by a tension spring 41 anchored to a post 42 extending from the panel 26. Pivo t ed on the lever 40 by a pin 43 is a latch arm 44 held in normal position by a spring 45 anchored to the lever 40. A laterally extending abutment lug 44' on the trip arm is in the path of a bracket 46 extending upwardly from the d sc 32, so that, when the disc is turned, this bracket will engage with the abutment .lug 44' to cause the lever 40 to swing with the disc, the spring 45 holding the lug 44 in abutting position relative to the bracket during such rotation of the dIsc and the lever therewith. Adjustably mounted on the base or supporting member 28 is a trip plate 47 which is engaged by the latch arm 44 just before the stop arm 36 on the disc 32 encounters the stop post 29 and further rotation of the disc and the lever 40 is stopped. Engagement of the trip arm 44 with the trip plate 47 causes the arm to swing sufiiciently to withdraw the stop lug 44 from the bracket 46, so that the spring 41 will then be free to swing the lever 40 back to its normal position. As before explained, rotation of the disc 32 is caused when the prospective purchaser turns the lever 4 and thereby turns the disc 6 whose post 17 engages the lever 34 secured to the d sc 32. When the purchaser releases the lever 4, the discs 6 and 32 are returned to normal posItion by the springs 12 and 37, respectively, the disc 6 then abutting against the stop pawl 9 and the disc 32 being held by the abutment of its arm 35 against the stop post 29.

Actuation of the lever 40 controls the operation of. mechanism for dispensing a drinking cup and also actuates mechanism for controll ng the. discharge of beverage into the dispensed cup. lVithin a housing 48 secured to the side of the supporting panel or frame 27 is a cup dispenser 49 for dispensing drinking cups from a stack 50. The dispenser may be of well-known design and forms no part of this invention. It has suitable escapement mechanism (not shown) fromwhich extends a lever 51, which, when swung laterally, operates the escapementmechanism for the one-by-one dispensing of cups from the stack 50, a dispensed cup dropping from the dispenser to rest on the floor 52 of the housing 48 in position to receive a charge of beverage. The dispensing lever 51 is connected with the actuating lever 40 by an adjustable rod or link 53, so that, when the lever 40 is swung itsfull distance, the escapement mechanism of the dispenser will be actuated and a cup discharged from the dispenser.

Describing now the beverage dispensing apparatus, a bell-crank lever 54 is secured to the front end of a shaft 55 which is journalled in the panel 26 and the frame 27 and at its rear end terminates in a head 56 within the frame 57 which forms a measuring chamher or space '58, the frame 57 being secured against the rear side of the frame 27 The vertical end of the bell-crank lever 54 .has a pm 59 on its lower end engaging in a end of a rod 64 which extends through an opening 65 in a bracket 66 extending from the panel 26.. Between the bracket 66 and the head 63, a compression spring 67 encircles the rod 64 for res'sting rotation of the lever 61. Stop-pins 68 and 69 extending from thepanel 26 limit the rotation of the lever 61 to either side of a neutral line extending through the axis of the-pivot stud .62 and the opening 65. After the level has been rotated through this neutral line position the compressed spring 67 will tend to rapidly rolate it the remainder of its movement into engagement with either of the stop posts.

The vertical leg of the bell-crank lever 54 has a lateral extension or bracket 70 having the hole 71 th'erethrough, through which extends a rod or link 72 which at-its inner end is connected with the actuat'ng lever 40 by a p'n 72' and which 'at its'outer end has the abutment 73 for engaging the bracket 70.

This abutment may be a nut threaded to the:

With

end of the rodeo that it is adjustable; this arrangement, when the lever40 3's swung as the prospective purchaser turns the lever 4, the abutment 73 will encounter the bracke 70 and the bell-crank lever 54 will be rotated.

When the bell-crank lever rotates, its pin 59 engages, and rotates the lever 61, :and, as soon as th's lever has been rotated throughv the neutral line herelnbefore referred to, the compression spring 67 will rapidly complete the,

rotation of the lever and of the bell-crank independently of the link 72. I

Referring to Figure 1,'clockwise rotatlon of the lever 40 will result in counterclockwise rotation of the bell-crank lever, and the lever comes to rest as soon as the lever 61 is stopped by its engagement with the stop post 68. Referring to Figure 2, the frame 57 has an inlet passage 74 connected with a pipe'7 5 with p which is connected a tank (not shown) containing the beverage. such as ginger ale, to

be dispensed; The inlet74 isconnected with the measuring chamber 58 by a port 76 which is controlled by a ball valve 77 locatedin the passageway 74. A' stem 78. extending from the valve 77 is guided in posts 79 and 80 on the frame 57 and,.at its inner end, is adapted to be engaged by the arm 81 extending from the head 56 secured to the inne'r'end of the 'shaft 55 to which the bell-crank lever 54 is secured. Between the guide posts 79 and 80, a spring 82 encircles the stem 78 with its lower end abutting against a pin 83 on' the rod and its upper end abutting against theguide' post 80, the spring resisting upward move ment of the stem 78 by the arm 81.

The frame 57 has a boss 84 providing the outlet passage 85 for the chamber 58. A plug 85 threadedly engages in the boss 84 and provides at its inner end a seat for the ball valve 86. A link 87 extends from .the ball valve through a passage 88 in 'thearm 89 extending from the head 56 in a radialdireetion opposite to that in which the arm 81 extends. A tension spring 90 within the passage 85 'is connected with the plug end and with the valve 86 and tends to hold the valve on its seat to closeflow through the outlet passageway 85.

The plug 85 is open to theflowiof beverage therethrough, andcommunicates with. a pipe 91 which terminates in a spout projecting into the-housing 48-below the dispenser 49 in position to charge beverage intoa cup which has beendispensed'from the dispenser and which will be supported on the floor 52 of the housing.

Normally, as shown on the drawings, the arms 81 and 89 on-thehead 56 of the shaft 55 are in such positionthat the arm 81 permits the spring 82 to hold the valve stem'7 8 to apply the valve 77 to its seat to close the inlet port 76, and the arm 89,'b.y its engagement with the head 87 of the link 87- will hold the valve 86 off its seat against the pull of the spring 90, so that the outlet from the chamber 58 is open. Whei1 the bell-crank lever 54 is rotated as a result'of rotation of the lever 4 by the prospective purchaser, the shaft 55, and, consequently, its head 56,) are rotated (counterclockwise, Figure *1 and clockwise, Figure 2), and such rotation causes the arm 81' to shift the valve stem 78 upwardly-to unseat thevalve '77, and causes the arm-'89 to release the tension on the link.87 so that the spring 90 may move the ball .86 to engage its" seat. The inlet to" the measuring chamber'58 is then opened andthe outlet therefrom is the supply tank into the measuring chamber.

The quantity of beverage delivered to the 'meas'uringchamber 58 is under control of the pressure to' which the liquid is subjected. Mounted on a bracket 93'which is supported from thepanel 26 is a pressure bellows 94 which is connected. by a pipe 95 with the measuring chamber 58 near thetop thereof. Above the head of the'bellows extends a lever 96 which is hinged at one end to the bracket- 93 and which carries an abutment 97 interme-1 diate its ends for engagement by thebellows head as the bellows is expanded. The other, end of the lever 96 carries a swiveled guide and abutment lug 98 through which a rod 99 is slidable,'this rod at its lowerend being connected With the outer end of thehorizontal member of the bell-crank lever 54-, the

rod at its upper end-having an abutment head 100. A tension spring 101 isconnected between the panel 26 and the lever 96 and" tends to hold the lever in lowered position. When the main operating lever 4 is turned the full distance by the purchaser, the bellcrank lever 54 will assume its lower position,

and in this position head 100 on the rod 99.

will be in engagement with or just abovethe' abutment lug 98 on the lever 96. As has already been explained, rotation of the bellcrank lever will result in opening of the measuring chamber inlet bythe valve 77 and closing of its outlet by'the valve 86.

The liquid under pressure enters the measuring chamber, and the air or gas within the.

measuring chamber is gradually compressed and flows through the pipe 95 to the pressure Figure 2). As soon as the bell-crank lever has been thus rotated a distance sufiicient to swing the lever 61 through its neutral or dead line, the compression spring 67 will then become efiective to rapidly swing the levers 61 and'54 to the ends of theirmovements. Such rotation of the bell-crank lever, transmitted through the shaft 55, will result in release of the valve 77 from the arm 81 and unseating of the valve "86 by the arm 89. The

measuring chamber is thus disconnected from the supply tank and is connected with the spout 92 so that the measured quantity of beverage in the measuring chamber may flow from the spout into the cup dispensed from the cup disperser. During suchoutflow of the beverage from the measuring chamber, the pressure is withdrawn from the pressure bellows which is then collapsedby the force of gravity aided by thepull of the spring 101, and all the parts of the machine are now in their normal positions.

Briefly summing up the operation, the prospective purchaser inserts a proper coin in the coin inlet, the coin dropping into the pocket 7 of the disc 6. The purchaser then to its extreme position with the lever61 turns the'lever 4 clockwise'the full distance, whereby, through the engagement of the post 17 with the lever 34, the disc 32 is rotated, which, by engagement of its bracket 46 with the abutment post 44' on the latch arm, carries with it the actuating lever 40. Through the connecting link 53, the dispenser 49 is operated to drop a cup into position below the spout 92, and, by means of the link 7 2, and, eventually, by the force of the spring 67, the bell-crank lever 54-1s swung abutting against the stop 68. This movement of the bell-crank lever results'in opening of the measurin chamber inlet by the valve .77

and closing 0? its outlet by "the valve 86, and also results in downward movement ofthe rod 99 to bring its head 100 to the abutment lug98 on the lever 96. The pressure bellows is now subjected to pressure and expands to swing the lever 96 upwardly and to draw the rod 99" upwardly to cause initial swing of the bell-crank lever 54 in reverse direction,

the final movement in such reverse direction sired, a door 102 may be provided for the" housing 48 which the prospective purchaser, after having deposited the coin and turned the lever 4, opens, so that he may withdraw the filled cup.

After discharge of the measuring cup con- I tents, the pressure bellows is relieved and collapses into normal position ready for the next operation of the machine.

Referring to Figure 1, it .will be noted that the abutment 73 is normally displaced from the bell-crank lever 54 so that this lever will not be rotated :until the lever 40 has been swung a certain distance when the prospective purchaser rotates the handle 4. The adjustment of the abutment73, and the adjustment of, the trip plate 47 for the latch arm 44 are such that, unlessthe prospective purchaser rotates the lever 4 the full distance in clockwise direction, there will be insufficient movement of the dispensing mechanism to dispense a cup from the dispenser 49 and also insutiicient initial movement of the bell-crank'54 to swing the lever 61 through its neutral or dead line, so that, upon release of the lever- 4 after only a partial rotation thereof, the dispensing machine parts will merely return to their normal positions without having accomplished any dispensation either of a cup or of beverage.

Holding of the operating leverv 4 after turning it the full distance will not interfere with the dispensing operation of the machine as the latch 44, upon engagement with the trip plate 47 at the end of rotational movement of the lever 4, will release the I Although I have shown one embodiment of the various features of my inventioh, it is to be. understood that changes and modifications may be made without. departing from the spirit and principles of the invention, and I, therefore, do not desire to be limited except as is specified in the appended claims.
